- This seems more of a statistics question than a probability question.
- You have a probability distribution with one parameter (k) and you
- want to estimate the value of k from a set of actual data, using some
- formula. But you need to make some kind of assumption about the
- distribution of k itself in order to ask your question. Suppose your
- formula gives k=29. I would guess that k=30 is much more likely to be
- the parameter for a real-life lottery in that case.

- I.e. every positive integer has a non-zero probability of being selected
- by the first ball? Then surely the distribution of this variable is not
- uniform, unlike every lottery I know of.
